BOLSTER-GUIDE FOR TRUCK-FRAMES.

Specification of Letters Patent.

Patented Aug. 2, 1910.

To all whom it may concern:

Be it known that I, HARRY T. ANDERSON, a resident of Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Bolster- Guides for Truck-Frames, of which the following is a specification.

This invention relates to bolster guides for truck frames, and more particularly to bolster guides for truck frames having integral cast side frames.

The object of the invention is to provide bolster guides which are movable out of engagement with the bolster to permit the removal and insertion of the bolster without taking apart the truck frame or otherwise disturbing the same.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is in part a side view of a portion of a truck side frame, and in part a vertical section thereof, showing my invention applied thereto; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1; and Fig. 3 is a vertical section on the line 33 of Fig. l.

The truck side frame is shown as an integral casting comprising the top chord 1 of general channel shape, the bottom chord 2 of general angle shape, and the columns 3, also of general channel shape in cross section. The usual bottom tie for the journal boxes is shown at 4. The side frames may be connected by any suitable transoms and are shown connected by the spring plank 5, which is shown as a rolled channel bar riveted between the columns 3 at their lower ends. The spring plank also serves as a seat for the springs 8 upon which rests the bolster 7. The latter may be of any desired or preferred construction.

The bolster guides 9 are shown in the form of castings pivoted to the channel columns at 10, and adapted to project through openings 11 formed in the web portions of the columns, and to enter recesses or notches 12 in the side faces of the bolster. These guides are held in position to engage the bolster by means of locking pins or bolts 13 passing through the side flanges of the columns and held in place by any suitable means, such as the cotter pins shown.

When it is desired to remove the bolster,

the pins 13 are removed on all four bolster guides and the latter swung outwardly and downwardly, as shown on the left hand of Fig. 1. The bolster can now be freely moved endwise to remove the same from the truck frame or to insert the same therein, and this can be done without taking apart or disturbing the truck frame as a whole or otherwise interfering with any part of the truck frame. hen the bolster guides are in their bolster engaging position they are firmly locked thereto and cannot get out of place and permit accidental endwise movement of the bolster.

What I claim is:

1. In a truck frame, the combination of side frames including vertical columns provided with openings therethrough, bolster guides comprising members pivotally mounted on the columns and arranged to project through said openings and engage the bolster or be swung outwardly to clear the bolster, and removable locking members engaging the free ends of said guides.

2. In a truck frame, the combination of side frames including vertical columns provided with openings therethrough, bolster guides comprising members arranged to project through said openings and having downward extensions pivoted to the columns, and removable locking members engaging the upper ends of said guides and holding the same in engagement with the bolster.

3. In a truck frame, the combination of side frames including vertical bolster columns of general channel shape having openings therethrough, bolster guides comprising members arranged to project through the openings in the columns and engage the bolster and provided with projecting portions receiving pivots extending through openings through the side members of the columns, and removable locking pins extending through openings in the side members of the columns and arranged to engage the free ends of the bolster guides and hold the same in engagement with the bolster.

In testimony whereof, I have hereunto set my hand.

HARRY T. ANDERSON.
